Abstract
A method is provided for manufacturing a fuel-cell stack that has a laminate including of a plurality of fuel cells that are laminated together. In each of these fuel cells, an MEA has an anode and a cathode joined respectively to the two sides of an electrolyte membrane is sandwiched between a pair of separators. The aforementioned method has the following steps: a sealing member layout step, in which fuel cells with sealing members applied at least between adjacent fuel cells are laminated together, forming a fuel cell module; and a pressure application step, in which pressure is applied to the fuel cell module in the lamination direction of the fuel cells, forming sealed regions from the sealing members. The lamination-direction thickness of the fuel cell module is controlled by controlling the amount of pressure applied to the fuel cell module in the pressure application step.
